Viscosity modifiers (Xanthan gum, Magnesium Aluminosilicate [Veegum])

Viscosity modifiers in agrochemistry: xanthan gum and magnesium aluminosilicate (Veegum)

Thickeners and stabilizers such as xanthan gum and magnesium aluminosilicate (known under the Veegum brand) are actively used in agrochemical production to adjust the viscosity and stability of liquid preparations, including SE (suspensions), herbicides, insecticides and liquid fertilizers. These components increase the stability of the formations, prevent their stratification and improve the adhesion of substances to the surfaces of leaves and stems.

Xanthan gum

Xanthan gum (food additive E415) is a biopolymer obtained as a result of the enzymatic processing of carbohydrates by the bacteria Xanthomonas campestris. It is completely soluble in water, resistant to extreme pH values (from 2 to 12) It retains stable properties over a wide temperature range from -18 °C to +120 °C. Due to these qualities, xanthan gum is a universal agent suitable for most liquid agrochemical compositions. It also shows synergy when combined with other natural thickeners such as guar gum or carob gum.

Veegum (Magnesium aluminosilicate)

Veegum is a purified clay mineral based on magnesium aluminosilicate used as a highly effective structurizer. Even at low dosages, it gives suspensions a stable consistency, preventing precipitation of solid particles. In addition, Veegum improves the rheological properties of emulsions and suspensions, facilitating their application and ensuring uniform surface coverage.

Fields of application in agrochemistry:

• Increased stability of preparations: prevents phase separation and precipitation in SE and other liquid forms;

• Viscosity adjustment: adjusts fluidity and consistency for optimal application;

• Compatibility with the components of the formulation: does not react undesirably with active substances, adjuvants and solvents.

Key Properties:

Xanthan Gum:

• Heat resistance and acid and alkali resistance;

• Compatible with natural and synthetic thickeners;

• forms pseudoplastic solutions that facilitate spraying.

Veegum:

• works effectively in low concentrations;

• prevents sedimentation and improves the texture of the product;

• promotes the uniform distribution of components over the surface of plants.

How to choose the appropriate viscosity modifier:

• Compatibility with active ingredients: check whether the additive is suitable for a specific formulation;

• Storage and application conditions: take into account the temperature regime and the acidity of the medium;

• Required viscosity level: select the modifier depending on the type and method of application of the drug;

• Economic feasibility: analyze the effectiveness per gram of active substance.

The use of xanthan gum and Veegum in suspensions and other agrochemical products contributes to the creation of stable, user-friendly and effective plant protection products and growth stimulants. Contact us. Our experts will help you find the optimal solution for your needs.
